DualHead2Go problem ?

[mal421]

Video and Projection etc. is not my natural domain but in recent months I have become more involved with it. I have a Matrox DualHead2Go(analogue) that cannot see either of two GeneTouch GT42MAZ screens. Every other screen or projector I have tried is OK. I have tried this with both a MAC and a PC with the same result. The screen displays 'No Cable' message and as far as the computers are concerned there is no Screen attached. I have connected the both GT42MAZ directly to both computers and all is how it should be so I'm guessing the Matrox unit doesn't see the screen for some reason or another. Has anyone else encountered this or a similar problem ?

Hi,

 

I've used a number of Matrox products, dual head's and triple head's in the past..

 

In my experience the analogue dualhead's are pretty much Plug and Play.. Are you using Matrox PowerDesk to manage your screens etc?

 

If you need a direct line to Matrox I have always found their support very helpful, they're based in Canada:

Are you using proper VGA cables? Some cables have missing pins and do not send the DDC / EDID so the matrox will not see screens attached with such cables.

 

cheers

As far as I am aware I am using standard VGA cables. The unit works fine with all other monitor and projectors. I suspect it may be DDC/EDID . I will try different cables on Monday.
